The U.S. is in the midst of a nuclear resurgence. However, as many nuclear startup leaders have already discovered, bridging the gap between research and deployment is more complex than many realize. For NANO Nuclear, managing the transition has become more efficient thanks to a partnership with a respected academic institution. “What's happening now in the space is that we’re going to actually build full-scale reactors and demonstrate that they work,” explains NANO Nuclear CEO James Walker. “We have a big construction project underway at the University of Illinois Urbana-Champaign to construct a full-scale micro reactor system and then have it licensed. We want this to be the first full-scale, licensed, commercial microreactor built in the United States.”
“By building these initial prototype reactor systems full-scale, we will demonstrate that this is a viable technology. It does work, it has a tiny footprint, it’s located in a central urban area without issue, and for the first time, people will be able to visualize how these systems will be part of their future cities, towns, and industrial operations. That will already go a long way to reassuring a lot of potential customers.”
The project is far more than an academic endeavor. It also involves state-level funding. In late 2025, Illinois Governor J.B. Pritzker awarded NANO Nucleara $6.8 million state funding grant to support the construction of its Illinois facility. This facility functions as a test run of sorts for the company’s KRONOS micro modular reactor (MMR). The modular design means that multiple units can be connected and used to fulfill even gigawatt-level power needs.
Illinois is currently the state with the most significant nuclear energy production, and this project is helping it stay true to that legacy.
The initiative is part of the Reimagining Energy and Vehicles in Illinois (REV Illinois) program, which in turn is part of the Illinois Economic Growth Plan. Because the project is expected to stimulate the state’s economy and substantially increase job creation, NANO Nuclear also received a REV tax credit. This academic partnership is an integral part of legitimizing nuclear energy in the eyes of the public.
“When the average person hears the word ‘nuclear,’ they think of the big nuclear reactors, mushroom clouds, and toxic waste. Then they think of all this bad stuff like Fukushima,” says Jay Yu, Executive Chairman and President of NANO Nuclear. “That's the level of paranoia the general public gets from nuclear power. But none of these fears can be associated with our reactor; it’s built to remove all the worst accident scenarios big nuclear plants may experience in worst-case scenarios. This will be the safest form of energy in the world.”
Decades of research and innovation have made nuclear energy much safer and more reliable, but changing public perception has proven to be more difficult. Shifting energy priorities have gradually begun to make a difference.
“Nuclear energy is no longer being treated solely as a clean power source but being positioned as a cornerstone of national security and data infrastructure,” Walker says. “AI data centers and defense systems both require enormous amounts of stable, uninterrupted baseload power, something renewables can’t provide on their own, even with huge footprints and massive storage systems. For the first time, we will have systems that can be put anywhere, output consistent baseload power, be zero carbon emitting, and can be co-located with urban areas or industry.”
“By formally linking nuclear to these priorities, the administration is reframing it as a strategic necessity rather than just an energy option, which is a fundamental shift in how the U.S. views its role in nuclear development.”
The University of Illinois Urbana-Champaign project is a pivotal one for the future of NANO Nuclear. However, it’s not the only construction project the company has planned. “Concurrently, we are also advancing a construction project in Canada, intended for location at the Canadian Nuclear Laboratory site at Chalk River,” Walker says. “We hope to be the first company in both the U.S. and Canada to construct a fully operational, full-scale, licensed commercial microreactor.”
Walker notes that the KRONOS MMR is just part of the picture. While the microreactor system project is well underway, NANO Nuclear is also pursuing other related endeavors.
“We are also progressing our fuel initiatives to involve ourselves in the nuclear fuel supply chain, partly to derisk the future mass production of our reactor, but also to open up many new commercial opportunities to our company. We also want to pursue other nuclear energy industries, such as the transportation and nuclear engineering services - both critical pieces of the supply chain puzzle,” says Walker.
The partnership between NANO Nuclear and the University of Illinois Urbana-Champaign is just beginning, and the success of the KRONOS reactor remains to be seen. But if the technology proves to be viable, it could usher in a new nuclear era.
